[ovs-dev] Bond support on Windows OVS

[Jinjun Gao]

Thanks for quick response, Alin.

If we use Windows team cmdlets, it will rely on Hyper-V role enable. Does it possible to support on disable Hyper-V role with your patchset (https://patchwork.ozlabs.org/project/openvswitch/patch/20181008232602.30924-1-aserdean@ovn.org/)?

     -AllowManagementOS $false

Hi Jinjun,



Basically we need to use `New-NetSwitchTeam` to make OVS aware of multiple adapters:

[1] https://docs.openvswitch.org/en/latest/intro/install/windows/#add-multiple-nics-to-be-managed-by-ovs<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.openvswitch.org%2Fen%2Flatest%2Fintro%2Finstall%2Fwindows%2F%23add-multiple-nics-to-be-managed-by-ovs&data=02%7C01%7Cjinjung%40vmware.com%7C6efeecbbd32d4dbe034d08d8482a70ff%7Cb39138ca3cee4b4aa4d6cd83d9dd62f0%7C0%7C0%7C637338694408254428&sdata=lrHnPpddOX2A1pHt4lpk8tAMOs6kzATGfWdwNd2VRoM%3D&reserved=0>



For bonding in particular we need to add some(or all) of those interfaces inside OVS bonds:

Please let me know if you want me to send a snippet that combines [1] and [2].



In particular use cases, we can also create a switch over LBFO team NIC as per:

https://docs.microsoft.com/en-us/powershell/module/netlbfo/new-netlbfoteam?view=win10-ps<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.microsoft.com%2Fen-us%2Fpowershell%2Fmodule%2Fnetlbfo%2Fnew-netlbfoteam%3Fview%3Dwin10-ps&data=02%7C01%7Cjinjung%40vmware.com%7C6efeecbbd32d4dbe034d08d8482a70ff%7Cb39138ca3cee4b4aa4d6cd83d9dd62f0%7C0%7C0%7C637338694408264418&sdata=fsYUFMfaQ%2FHD1JI3wlOHtmTcyDXGHs%2ByQ6UVUantwo8%3D&reserved=0>

but in that case from the OVS side we see one single external NIC.



Thanks,

Alin.

Hi Alin and Anand,



I'm investigating how to support bond with dual or more physical NICs on Windows OVS.  I heard from Anand that you ever discussed it with community guys and had a good idea about how to implement it. Can you please provide some input on it to us?



Thanks,

-Jinjun
